I think Hitler's extreme Nationalism is clearly a right wing attribute but his strong centralized management of the German economy for a so called "greater good" is a leftist attribute.I think the terms left and right wing come from the French revolution and where each group was seated.

It's interesting how little attention is focused on Stalin a leftist dictator who possibly murdered twice as many people as Hitler as well as a slew of other leftist dictators like Mao,Pol Pot,and several Kim Jung's from NK.

We must never forget who gave the Soviets the secret of the Atomic Bomb. That would be the leftist, Communist-loving traitors, Julius and Ethel Rosenberg. Both of them went to the electric chair in the 1950's. Nor should we forget who gave our nuclear secrets to North Korea. That would be the leftist traitor, Bill Clinton. Nor can we forget who enabled Iran to get nuclear weapons. That would be the leftist traitors, Barack Obama and John Kerry.

Quotes from Dnesh D'Souza's "The Big Lie" subtitled "Exposing the Nazi Roots of the American Left".

Hitler (the Nazi) saw himself as a National Socialist, not a fascist, but the two ideologies are related in that they are both based on collectivism and centralized state power. They emerge, one might say, from a common point of origin. Page 67 Paragraph 2One distinction between the two is that fascism had no intrinsic connection with anti-Semitism.

Hitler was, like Mussolini, a man of the Left. Page 68 Paragraph 1

...all the leading figures in the founding of fascism were men of the Left. Page 68 Paragraph 2The first fascists ... were almost all Marxists.

In all the articles comparing Trump to Mussolini I searched in vain for references to Mussolini's erstwhile Marxism and lifelong attachment to socialism. Page 69 Paragraph 3

Even though Lenin and Trotsky differed on relatively small points of doctrine (to the degree that Lenin ordered Trotsky's death), they were both men of the left. Page 70 Paragraph 2I will prove that fascism is exclusively a product of the Left. Paragraph 3

My goal is to show the base origins of fascism ... and to put to bed once and for all the big lie that makes fascism a phenomenon of the Right. Without this lie, the claim that Trump and the GOP are fascists simply crumbles. Page 71 Paragraph 1
